Improvement in carriage-wrenches



IVILBUR F. ROIVE, OF MINNEAPOLIS, MINNESOTA.

IMPRQVEMENT IN CARRiAGE-WRENCHES.

Specification forming part of Letters Patent No. Hlfilfi, dated May 26,1874; application filed April 18, 1874.

To all whom it may concern:

Be it known that I, YVILBUR F. ROWE, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and ImprovedOarriageWVrench, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a sectional sideelevation of my improved carriage-wrench; and I i g. 2, a top view ofthe same, partly in section, on line 0 c, Fig. 1.

Similar letters of reference indicate corresponding parts. v

The object of my invention is to provide, for the purpose of removingand replacing the axle-nut of carriages, an improved wrench, by whichthe same can be attended to in a neat and quick manner, without soilingthe fingers or letting the nut come in contact with dirt, sand, or otherimpurities.

My invention consists of a ca-rriagewrench, which slides on the shank ofan axle-nut socket, the shank being partly polygonal, partly round, andprovided with a button or knob, by which nut and socket maybe turned,while the starting or finishing turns of the nut are given by the leverpart of the wrench.

in the drawing, A represents a carriagewrench of the usual shape, whichis supplied at one end with rectangular recesses of various sizes forditi'erent sizes of nuts. The other end of wrenchAhas a square hexagonalor polygonal recess, and slides therewith over the shank C of a socket,I3, having the size of the axle nuts, one part of the shank being of ashape to correspond exactly to the recessed end, while the other part ofthe shank C is round, its diameter being equal to, or somewhat smallerthan, that of the inside tangential circle of the polygonal part. Theshank is provided with a button or knob, D, by which the socket B mayeasily be turned in the end of the wrench, when the same is carriedover'the round part of the shank, the wrench taking firmly hold of thesocket when placed on the nut-shaped polygonal part of the same.

For removing the axle-nut, the socket is placed 011 the same andloosened by the lever action of the wrench thereon. The lever is thenslipped oif onto the round part of shank, and the nut taken off byturning the socket and nut at the head or knob with the fingers, thelever holding meantime the socket in position on the nut. The nut,together with the socket, is laid down, button downward, the wrenchresting thereon, and preventing thereby the comin g in contact of thenut with dirt. When the axle is cleaned and oiled the nut is carriedback into position thereon, turned on by the fingers and socket, andthen firmly tightened by the lever action of the wrench by placing thesame on the polygonal part of the shank.

As the lever is not required to be turned with the nut, the taking offand putting on of the nut is attended to easily and rapidly, and a veryconvenient carriage and wagon wrench obtained thereby.

Having thus described my invention, I claim as new and desire to secureby Letters Pat cut- 1. The improved carriage or wagon wrench consistingof lever part A, with polygonallyrecessed end applied to the axle-nutsocket B, having a shank, G, of partly polygonal, partly round, shape,and button or knob D, constructed and operated substantially as and forthe purpose set forth.

2. An axle'nut socket provided with a lower recessed part, fitting theaxle-nuts of awagon or carriage, a shank part of partly polygonal,partly round, shape, and a top knob or button, substantially as and forthe purpose described.
